Notes

When ordering, please specify packaging code: e.g. CV9052-ALC
Inductance is tested between pins 1 and 3 at 100 kHz, 0.05 Vrms, 0 Adc.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance is for the primary, measured at 100 kHz, 0.05 Vrms, 0 Adc with the secondary windings shorted.
1500 Vrms, one minute isolation from primary to secondary.

Termination:

RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze terminations.

Packaging:

C = 7″ machine ready reel. EIA-481 embossed plastic tape (500 per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
D = 13″ machine ready reel. EIA-481 embossed plastic tape, factory order only, not stocked (1200 per full reel).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
